Embodiment 1

[0029] A method for grafting large branches of golden camellia, the grafting time is March 15, 2017, and the specific operation steps are as follows:

[0030] (1) Rootstock selection: Select the above-mentioned spare 10-25-year-old, vigorous-growing, and free-growing Hongluzhen camellia adult plants as rootstocks, cut off the branches at a distance of 1.5-2.0m from the ground, and keep 6-8 dry branch angles. 1. For main branches with balanced distribution and strong growth, 3 to 4 side branches are reserved for each main branch as rootstocks for grafting, the remaining branches are cut off, and 2 to 3 small branches are reserved as vegetative branches to provide nutrients;

[0031] (2) scion selection: select the superior plant of camellia japonica with many flowering numbers, large flower types and strong adaptability as the mother plant, and cut large branches with a diameter of 0.8 to 1.5 cm from the middle and upper part of the mother tree as the scion;

[0032] (3) Rootst...

Abstract

The invention discloses a camellia nitidissima bough grafting method. The camellia nitidissima bough grafting method comprises the following operating steps: (1) rootstock selection; (2) scion selection; (3) rootstock treatment; (4) scion treatment; (5) grafting: embedding scions into V-shaped grooves of a rootstock, tightly combining two sides of the scions, tightening joints by using thin iron wires, enabling excessive parts after tightening to face downwards, then binding the joints by using a thin film, wrapping the scions by using the thin film, wherein the excessive iron wire is not completely wrapped by the plastic thin film, so that the joints are free of water accumulation and can be kept breathable; and (6) management after grafting. According to the method, the grafting survivalrate of camellia nitidissima is increased, growth and flowering of scions are promoted, the cultivation period of large-size plants is shortened, and the method has a good promotion effect on development of camellia nitidissima industry.
